In order to draft with only 4 people (my playgroups never have more than 4 people), I've adapted the Degenerate Micro Cube (found here: https://cubecobra.com/cube/list/degenerate-micro-cube), cutting it down to 96 cards. It uses the gameplay rules adapted from Max Hero’s 15 Card Singularity format:

• Cards are drafted in 2 packs of 12 cards
• The minimum deck size is reduced from 40 cards to 15 cards
• Players do not lose the game if they would draw a card from an empty library

Like its source of inspiration, this Nano Cube contains several of Magic’s most broken and degenerate strategies. The present macro-archetypes are better described as combo, stax/prison, and control, rather than the more prevalent aggro, midrange, and control.

In order to give as much space in this cube to each strategy as possible, I've moved a number of lands to this cube: https://cubecobra.com/cube/overview/oway to be drafted after drafting the Nano Cube.
